But that doesn't mean Adobe isn't interested in HTML5 and CSS3--the updates to Hypertext Markup Language for describing Web pages and to Cascading Style Sheets for Web page formatting--that are two of the most important parts of that Open Web work. After all, Adobe does have its DreamWeaver product for Web site development.

But there's a new sign that Adobe is taking more interest in Open Web work. Last week, it launched its Design and Web blog, written by Paul Gubbay, senior director of engineering, and Lea Hickman, senior director of product management for the Creative Suite design and Web tools, suites, and services.

So far the pair have hinted that Adobe is working on some more powerful tools for HTML5 and CSS3, with internal demonstrations of what can be done, though no promises of shipping anything anytime soon.

"Recently, we attended technology demos across our design and web products. We saw a range of prototypes, many of which were focused on new services, multiscreen authoring leveraging HTML5 and CSS3. We have been spending a lot of time internally thinking about how our tools can best support and take advantage of some of the new functionality in HTML 5, and we wanted to share a couple of early ideas with you," they said, offering a demonstration of the Canvas technology for 2D graphics through HTML5 in one post.

"There has been much discussion around whether or not HTML5 and CSS3 will make it easier for designers to reach new devices," the two wrote. "We think it will."

Web standards are experiencing something of a renaissance. The World Wide Web Consortium--of which Adobe is a member--has in recent years returned to HTML development after a years-long hiatus focused on XHTML 2.0 technology that didn't catch on.

A new version of Adobe's Creative Suite products is due to arrive soon, but these demonstrations won't be showing up in the software, the two said.

"We'd like to share some of these with you to get your feedback and see what resonates," Gubbay and Hickman said. "To be clear, we are giving you a very early view. It won't be in the next version of CS."
